Product Description
Danfoss KRR Series Axial Piston Variable Displacement Pump
Product Overview: The Danfoss KRR series is a high-performance swashplate axial piston variable pump specifically engineered for Open Circuit systems. This series is widely utilized in forklifts, compact loaders, municipal vehicles, and various medium-power industrial power units. Renowned for its exceptional power density and rugged internal construction, the KRR range delivers stable pressure and flow output even in the most demanding environments. Whether the specialized KRR045DPC17NN or the standard KRR038, this series sets the benchmark for reliability in hydraulic transmissions.
Key Technical Advantages:
Precise Pressure Control Logic (DPC): Models like the KRR045DPC17NN… are equipped with an advanced Pressure Compensator (DPC), which automatically modulates displacement based on system demand. This improves operational precision while significantly reducing energy loss.
Optimized for Mobile Machinery: Designed for the frequent load variations typical of mobile equipment, the KRR series features reinforced swashplate bearings and wear-resistant piston groups, ensuring an extended service life under high-temperature and high-pressure conditions.
Low Noise & High Volumetric Efficiency: Utilizing an acoustically optimized housing and precision-ground port plates, the pump operates at reduced decibel levels—meeting modern environmental standards for construction sites while maintaining maximum efficiency at 260 Bar rated pressure.
Flexible Modular Interfaces: Offers various shaft splines (e.g., NFA6) and flange configurations (e.g., NPL), ensuring seamless integration with mainstream engines and gearboxes, which simplifies both installation and field maintenance.
Specific Models & Technical Parameters:
Core Series: KRR038, KRR045.
Detailed Configurations: Supports complex codes like KRR045DPC17NN NNN3C2NFA6NPL BNNNNNN.
Displacement Specs: 38 cm³/rev, 45 cm³/rev.
Pressure Specifications: Rated operating pressure 260 Bar (26 MPa); Peak pressure up to 350 Bar.
Mounting Interface: Compliant with SAE standard flanges and spline specifications.
